(57) [Summary] (Correction) [Purpose] To provide a safe staircase that is easy to ascend and descend without ergonomics. [Structure] In the round staircase part where the traveling direction is changed by 180 degrees in the middle of the stairs, the step board 2 which is fixed to the sasara girder and the wall 1 so that the step end line is 90 degrees is followed by one step forward. The step plate 3-1 has a step end line of 60 degrees with respect to the step plate of the step plate, the step plate 3-2 has a step line of 30 degrees, the step plate 3-3 has a step line of 30 degrees, and the step line has a step line of 60 degrees. 3-4 degree tread
Surrounding stairs featuring a surrounding part that is fixed in the order of.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a staircase.

[0002]

[Prior art]

 Conventionally, the round stairway portion that changes the traveling direction by 180 degrees in the middle of the stairs is a step plate of a straight-ahead portion fixed to the sasara girder and the wall 1 so that the step end line is 90 degrees as shown in FIG. Following step 2, four step plates 3 each having a step end line bc, d, e of 45 degrees with respect to the step end line a of the previous step plate are sequentially fixed and formed in the surrounding portion.

[0003]

[Problems to be solved by the device]

 By the way, in the case of changing the direction of 180 degrees with the step plate 3 having a conventional step end line of 45 degrees, the tread surface of each step is a little too wide in order to go around each step of the four steps in one step. It took two steps to go around the stairs, and it took a total of eight steps to change the direction at the stairs.

In recent years, in particular, slip accidents frequently occur when the elderly and children move up and down, and it is necessary to construct stairs that are ergonomically acceptable and that can be safely and reliably moved up and down. The placement was a problem.

In view of this, the present invention has been devised as follows for the purpose of providing a safe staircase that is easy to move up and down without ergonomically.

[0007]

[Means for Solving the Problems]

 That is, the present invention was devised to solve the above-mentioned problems, and the step end line is fixed at 90 degrees to the sasara girder or the wall at the round staircase portion where the traveling direction is changed 180 degrees in the middle of the stairs. Next to the straight part of the straight line, a step plate with a step end line of 60 degrees, a step board with a step end line of 30 degrees, a step board with a step end line of 30 degrees, and a step end line It relates to a turning staircase having a turning portion fixed in order of a 60-degree tread.

[0008]

[Action]

 In the present invention, the step end line is fixed to the turning portion in the order of 60 degree tread, 30 degree tread, 30 degree tread, and 60 degree tread, which means that when going up and down the stairs, This is because it is possible to move up and down in one step with a tread of 2 steps or 30 degrees.

[0009]

【Example】

 The present invention will be described below with reference to the drawings of the embodiments.

Reference numeral 1 denotes a sasara girder or a wall, to which a stair tread is fixed.

The tread is made of wood, metal, synthetic resin, inorganic material or the like, and in the case of concrete construction, the wall and the tread may be integrated. As the dimensions of the footboard 2 used for the straight-ahead portion, a width of 75 to 100 cm, a tread surface of 15 cm or more, and a rise of 23 cm or less are standard.

When the tread plate is made of wood used for general houses, a tread plate having a thickness of 2 to 4 cm, a width of 90 to 100 cm, and a tread surface of 24 to 26 cm is suitable.

Next, as shown in FIG. 1, the tread plate 3 used for the surrounding portion is a tread plate (3-1, 3-) in which a substantially square tread plate is divided into 60 degrees and 30 degrees from one corner. 2, 3-3, 3-4), and the thickness, width, rise height, etc. are the same as those of the footboard 2 of the straight-ahead portion.

Continuing with the step plate 2 of the straight-ahead portion, a step plate (3-1) having a step end line α of 60 degrees and a step plate having a step end line β of 30 degrees with respect to the step end line a of the previous step plate. (3-2) Step plate (3-3) with step end line γ of 30 degrees, Step plate (3-4) with step end line δ of 60 degree Form.

[0015]

[Effect of device]

 As described above, the turning staircase of the present invention is constructed by combining the step plates with the step end lines of 60 degrees and 30 degrees in the turning section, so that the step step of the 60 degree part can proceed in two steps as usual. Since it is possible to proceed in one step on the 30 degree step plate, not only can the number of steps to go up and down the stairs be reduced by two from the conventional stairs, but it is also a step that facilitates continuous progression, and the occurrence of accidents is suppressed. It has the effect that it can be done.
